Project planning information• Changes to the time range and function take effect only if they

are made when de- energised.

Do not activate Start input B1 or B3 until supply voltage isapplied.

• Same potential applied to A1 and B1 or A3 and B3.

• Same potential applied to A1 and B1 or A3 and B3.In the case of dual-voltage versions, connect only on voltagerange in each case.

• In the case of AC, it is not permitted to control loads in parallelwith the Start input (see adjacent sketched circuit diagrams).

Monitoring relays

Standards and regulationsThe monitoring relays comply with:• IEC 721-3-3 "Ambient conditions"• IEC 1812-1DIN VDE 0435, Part 2021 "Electrical relays"• IEC 1000 "Electromagnetic Compatibility"• IEC 947-5-1; DIN BDE 0660, Part 200 "Low-Voltage Switchgear Devices"

Scope of applicationMonitoring relays are used in industries and plants, also in building technologies, distributionsand computering systems.They provide for higher safety in operation, monitoring voltage, currents, phase sequences,motor parameters, liquid levels, insulation between power and earth.The relays control important parameter for operations and give warning and/or alarm signal forswithing off or on.Parameter and limits - for example undervoltage or overvoltage - can be adjust.

Customer benefits are:• industrial design• high accuracy• high reliability• easy handling

Housing designThe monitoring relays are suitable for snap-on mounting on 35 mm top-hat rails toDIN EN 50 022.


Compact electronic monitoring relaysType C 55x / C58x

Neither overload nor underload ...

... are particularly good for machines and installations in industrialapplications. An unsteady power supply may lead to machine failureand, thus, expensive downtimes. Consequently, electrical parameterssuch as voltage, current, phases, power factor (cos ϕ) and filling levelsof conductive fluids should be monitored carefully and professionally.

The electronic monitoring relays ...

... of Series C 55x from ABB are simply versatile in use. This extensiverange offers various relays for detection and monitoring of electricalparameters such as current, voltage, phase imbalance, phase failureand phase sequence in single-phase or three-phase power systemsand filling levels of conductive fluids. Thus, relays C 550 to C 552 makeit just as easy to protect installations and machines against overvoltageand undervoltage as they do to monitor currents in AC or DC powersystems. Relays C 556 monitor overvoltage and undervoltage in 3-phase power systems with and without neutral conductor whilst unitsC 554 and C 557 monitor phase failure, phase sequence and phaseimbalance. Relay C 559 for power monitoring (cos ϕ) is used for controltasks on machines and to protect the machines against underload or

The ergonomic design of theoperating controls allows easy and precise setting and the design andcoloration of the monitoring units of Series C 55x match those of theentire range of ABB switchgear devices. The relays are mounted eitheron a 35 mm DIN rail by snapping them on or with screws on a mountingplate. It suffices to slide the retaining springs a little on the undersideof the unit (not on C 550). It goes without saying that all units of theC 55x Series are particularly rugged and designed for use in roughindustrial atmospheres. The UL and CSA test marks permit worldwideuse and it goes without saying that all relays bear the CE mark.

Basic mode of operationCurrent monitoring withoutlatching

As soon as the value of the alterna-ting current or direct current to bemoni-tored reaches the thresholdvalue set on the front panel, the out-put relay drops out after expiry of theset time T1. The relay picks up imme-diately again when the current hasreached the hysteresis value again.

Current monitoring with latching

If the set limit value is reached, theoutput relay drops out after expiry ofthe set time T1 and remains latchedin this position even if the measuringcurrent once again assumes a per-mitted value.

Function overcurrent (OVER) andundercurrent (UNDER)

Owing to the ON delay T2, currentpeaks (function OVER) resp. currentfades (function UNDER) which mayoccur on make do not lead to a chan-ge in the relay state. The delay timeT1 prevents a disturbing, constantswitch-on and switch-off of the relayif the measured value is near to theset threshold value.

Basic mode of operationRelays for phase monitoring monitorthe phase sequence and failure ofone of the three phases. No settingsare required during operation. If thephase sequence is correct and noneof the three phases has failed, theoutput relay picks up after the delaytime T1 and the LED lights. In theevent of a phase failure or fault, theoutput relay drops out after the delaytime T2 has elapsed and the LEDgoes out.

If a phase sequence error occurs onswitch-on of the voltage, the relaydoes not pick up.

Note:

Relay C 554 is not protected againstreverse voltage. If there is a risk ofenergy recovery from a motor in theevent of phase failure, relay C 557with monitoring of phase asymmetrycan be used.

Basic mode of operationThe basic mode of operation is basedon measurement of the impedance ofthe fluid between two submersibleprobes. If the measured value is lessthan the threshold value set on thefront panel, the actual relay changesits circuit state. In order to precludethe effects of electrolysis phenome-na, the probes operate with AC.

Regulating two levels

The output relay changes its circuitstate as soon as the fluid levelreaches the maximum probe whilstthe minimum probe is immersed. It returns to the original circuit stateas soon as the minimum probe is nolonger in contact with the fluid.

Basic mode of operationThe output relay picks up as soon asthe values of the three star voltages ofthe phases with respect to the neutralconductor lie between the lower andupper threshold value. The thresholdvalues are set separately via twopotentiometers on the device frontpanel.

Ordering details

Princip of FunctionThis relay monitors stillstand and un-der speed levels.

By system start, a monitoring delaytime from 0.3 ... 30 sec is adjustable.For this delay time the measuringsignals are locked. The relay doesn’tact.

For more than 30 sec the externalcontact „S2“ is to be closed and canbe opened if the start has finished.In this way the customer can state aflexible delay time.

Customer can adjust a time between2 measured pulses.If the time tolerance is out of theadjusted range – the relay will switchby underlimit not by over limit. If thespeed level comes in the normal ran-ge again the relay will go back innormal position.

By using a measuring voltage, max.30 V the relay will give also a contactby under limit.

Measuring inputs are:

• Puse signal of 3-contact

• Namur pulse signal

• Potential free contact

• Voltage signal

Zero speed monitor Type C 581Technical data

Self-testWhen starting on via the A1-~ the following testingsequence is carried out:

The relay outputs (terminals 13-14 and 21-22)pick up for 1.5 sec. and then drop out for 1.5 sec.If no fault is detected, they then pick up again.The following checks take place:

• Maloperation of the output contacts(terminals 13-14 and 21-22),

• Failure of one of the phases L1, ~ or L3,

• Validity of the feedback loop (XI ->(2),

• Failure of an internal component

Safety functionIf an electric motor turns without being fed acurrent it behaves like a generator and producesa voltage at the terminals of its windings.This so-called retentive voltage depends on thefollowing conditions: speed, motor properties,residual magnetism and inertia of the mechanical

component. The zero-speed monitor C 581 measu-res this voltage and allows an opening of the doorsor guards only after the motor is at a standstill.

SettingThe individual channels are set separately with thehelp of 2 potentiometers on the front of the C 581.In this way any asymmetries in the windings or theretentive voltages can be compensated. Thesettings between 20 and 500 mV can be done insuch a way that the threshold is equal to a lowspeed or zero speed and does not impose a risk tothe operator.

Control elementsThe zero-speed monitor C 581 has a NO safetycontact (13-14) and a NC safety contact (21-22).Within the lines of the switching capacity of thesafety contacts (1500 VA) one or more switchingelements can be connected.

Insulationmonitoring device

additional equipotentialbonding

The IT system is supplied either from an isolation transformer or anindependent voltage source, such as a battery or a generator. Thepeculiarity is that no active conductor is directly connected to earthin this system. The advantage of this is that only a small fault currentcan flow in the event of an insulation fault. This current is essentiallycaused by the system leakage capacitance. The upstream fuse doesnot respond, thus maintaining the voltage supply - and therforeoperation - even in case of a phase-to-earth fault.

The high reliablitity of an IT system is guaranteed thanks to conti-nuous insulation monitoring. The insulation monitoring devicerecognises insulation faults as they develop, and reports that a valuehas fallen below the minimum immediately, before an unforeseeninteruption of operation is caused by a second insulation fault.

The following illustration shows the typical arrangement of an ITsystem.

• chort-circuit and earth fault currents may cause fires anddestroy parts of the plant

• high costs are incurred due to interruptions of operation,damage and losses

Without adequate insulation resistance

• protection against direct contact is not guaranteed

• protective arrangements against overcurrent or fault currentswill frequently drip out and interrupt operation

The motor temperature is measu-red by so called PTC thermistortemperature sensors, that normally havealready been embeded inside the motorwindings by the motor manufacturer.The thermistor machine protectiondevice Custorapid® can easily beconnected with the motor via cable.There is no need for further adjustment.

Advantages• High precision in temperature measurement

through PTC temperature sensors in the motor

• ABB Thermistor machine protection Custo-rapid® can be installed directly in the switch-box

• Incorporated possibility for the integration ofprocess automation through the functionshand/automatic reset

• Robust by design

• Highly reliable

• Simple handling for planing, project-designand installation

ABB offer PTC sensors for differnt temperatures limits: 70 ... 170 °C

If the temperature of the motor grow over the sensor limit, the relay will switch. After coolingdown the relay will switch again and can start the motor.

General information

Mode of operationThe thermistor machine protection control units Custorapid® C505 andC506 operate according to the closed-circuit principle and thereforeself-monitor even against discontinuity in the connection voltage.A short-term voltage drop of less than 200 ms (100 ms in the case ofwide-span voltage units) does not cause a change in state of theoutput contacts. Control units C506.12 and C506.15 are additionallyequipped with short-circuit detection in the sensor circuit. In the

event of a short circuit in the sensor circuit (resistance in sensorcircuit < 20 Ω) the device is tripped. This equipment state is indicatedby flickering of the TRIPPED LED. Control units C506.12 are alsoequipped with dynamic discontinuity detection (flashing of theTRIPPED LED). The control units have electrical isolation betweenthe control circuit and sensor circuit (24V DC versions have noelectrical isolation).

The PTC thermistor temperature sensors (temperature-dependent with positive temperaturecoefficient) must be selected by the manufacturer of the motors depending on:

• the motor insulation class to IEC Publication 34-11• the motor utilisation category• the special characteristics of the motor, such as conductor cross-sections of the windings,

permissible overload factor etc.• special conditions prescribed by the user, such as permissible ambient temperature, risks resulting

from locked rotor, extent of permitted overloading etc.

One temperature sensor must be embedded in each phase of the winding. In the case of three-phasesquirrel cage motors for instance, three sensors are embedded in the stator winding. For pole-changingmotors with one winding (Dahlander connection), 3 sensors are also sufficient. However, pole-changingmotors with two windings require 6 sensors.If a preliminary winding is required before the motor is switched off, separate sensors for a correspondinglylower temperature must be embedded in the winding. They are connected to a second control unit.The sensors are suitable for embedding in motor windings with rated operating voltages of up to 660 V AC.Conductor length: 500 mm per sensor.A 14 V DV varistor can be connected in parallel to protect the sensors from overvoltages. Because of theircharacteristics, the control units can be used with thermistor sensors of other manufacturers to DIN 44081 and DIN 44 082.

Test/reset buttonThe tripped device can be reset with the blue button (only onC506.xx), provided the sensor circuit(s) have cooled down again(< 1500 Ω). In addition, the test function can be invoked andtripping simulated in the non-tripped state by depressing thebutton > 2 s.

Remote resetWith a floating NO contact at terminals Y1 and Y2 (not on C505.xxand C506.03) the tripped device can be reset provided the sensorcircuit(s) have cooled down again (< 1500 Ω).

Auto resetDevices C505.01 and C505.02 reset themselves automaticallywhen the sensor circuit has cooled down. This function can berealized in devices with remote reset by means of an externaljumper between terminals Y1 and Y2.

Short-circuit detection:

Control units C506.12 and C506.15 constantly check the sensor-circuit resistor for short circuit. Sensor circuit resistances < 20 Ωcause the device to trip. The TRIPPED LED flickers.

Non-volatile storage

Control units C506.02, C506.12, C506.15, C506.22 and C506.62 storethe device state (tripped / not tripped) in an EEPROM. In the event ofmains failure, this state is retained and is restored on resumption ofpower supply. On the C506.15 with bistable output relay, the positionof the output contacts is also retained on interruption of supply.

Dynamic discontinuity monitoring

Control unit C506.12 with dynamic discontinuity monitoring evaluatesthe rise time of the sensor circuit resistance. If the sensor circuitresistance rises within 200 ms from 3600 Ω to 12 kΩ , the devicedoes not just trip, but also indicates the discontinuity by flashing of theTRIPPED LED.

Notes

In the case of tripping devices with DC operation, electrical isolation must be ensured by means ofa battery network or a safety isolating transformer according to DIN VDE 0551.

If tripping devices with AUTO RESET are used in EEx e applications, it must be ensured by thecontrol wiring that the machine being monitored does not restart independently.

In the case of tripping devices without short-circuit detection, the sensor circuit resistancemust be measured with a suitable measuring device on initial startup. In the case ofresistances < 50 Ω the sensor circuit must be checked for short circuit.

If using device C505.01 (no READY LED) or C506.15 (no change of switching state of output relayif control voltage fails) to protect EEx e motors, separate monitoring of the control voltage isrecommended.

If machines are equipped with PTC thermistortemperature sensors to DIN 44 081 or DIN 44082, the control units with test mark may also beused in place of control units stipulated in thePTB test certificates in each case.
